Patient safety: is it just another bandwagon?

In this paper, the author questions the focus of the patient safety movement, speculating that it might be just another "bandwagon" that health executives and some health professionals are eager to join. The history of this current emphasis on patient safety is briefly sketched, including current activities in Canada, and questions are raised about whether the movement aids or avoids pressing healthcare issues, many of which are supported by good evidence. These include the relationship between nursing staffing and patient outcomes, the way in which a "cult of efficiency" has operated to make errors more likely and how the silencing of nurses and other staff leads to error. Whether or not one considers the current focus on patient safety a bandwagon, it is important to reflect critically upon the activities undertaken to address the issue and to determine whether one should jump on this bandwagon.     

Inadvertent hypothermia: is it just a perioperative problem?

Patients undergoing surgery run the added risk of inadvertent hypothermia. This article suggests that simple measures undertaken in the ward can prevent this serious perioperative problem.     

Social roles and long-term illness: is it time to rehabilitate convalescence?

The total extent of sickness in the population has increased while disease has decreased. Being sick is a role that offers the patient many advantages both directly, in terms of being absolved from undertaking many daily activities if necessary, and indirectly, through additional financial and other resources that may be offered. Because of these advantages, it is usual for any persistent sickness to be validated by health care professionals. Moreover sick people are expected to make every effort to leave the sick state, especially to make every effort using offered advice and resources such as rehabilitative treatments. However some people are sick longer than anticipated or apparently justified. The sick role developed based on assumptions that may no longer be valid, and the extended World Health Organization's International Classification of Functioning (WHO ICF) model of illness provides a new analysis of the problem, emphasizing that sometimes sickness is caused or perpetuated by factors other than disease. Among other factors, the lack of a way out of the sick role might be one reason for increasing sickness. Therefore re-establishing convalescence as a role might facilitate people in leaving the sick role, and rehabilitation should consider promoting convalescence.     

The healing power of art: is it just for patients?

To be a caring professional one must learn to care for oneself. This article is an exemplar of one nurse's discovery of the use of music to cope with stress and grief.     

Erythropoietin in the critically ill - is it more than just blood?

Erythropoietin (EPO) has been in clinical use for the treatment of anemia for over 15 years. Recently it has been demonstrated that EPO has actions other than stimulating the bone marrow. It has been suggested that due to its tissue protecting effect, EPO may be effective in improving outcome in the critically ill.     

Three-dimensional ultrasound in small parts: is it just a nice picture?

For longer than 40 years, ultrasound (US) has been a widely used imaging tool in medical practice, which has proved helpful for the diagnosis and staging of diseases. Although three-dimensional ultrasound (3D) US has been available for more than 10 years, it was only through the development of the most recent computer technologies and its adaptation to ultrasound systems, that 3D US has become able to achieve the high level of sensitivity and performance necessary to be considered seriously in clinical practice. 3D US is rapidly turning into a technology with an ever-increasing range of applications in numerous fields because, among other reasons, it helps overcome some of the key limitations related to two-dimensional imaging. 3D US can be used in ultrasonography for small parts, among other medical areas. The assessment of the testicle, parotid, thyroid and parathyroid glands is properly achieved. The multiplanar presentation and niche mode are quite useful to determine the extension--inside or outside the organs-, of nodules, cysts or tumors. The volume measurement is better assessed with 3D US and given this, we can perform studies that follow growth in order to decide medical or surgical treatment. The VOCAL makes it possible to obtain a proper after-treatment follow-up of focal disorders in these small organs. Neovascularization is clearly viewed with 3D US and probably can suggest malignant origin of a neoplasm. 3D US offers a more comprehensive image of anatomical structures and pathological conditions and also permits to observe the exact spatial relationships. We are aware more studies are needed to demonstrate specificity and sensibility of 3D US in particular clinical conditions, not only in small parts but also is some other non-Ob/Gyn applications.     

Macroprolactin: what is it and what is its importance?

Monomeric prolactin (PRL) of molecular weight 23 kDa constitutes up to 95% of adult serum PRL. Macroprolactin is a large antigen-antibody complex of molecular weight greater than 100 kDa and constitutes less than 1% of circulating PRL. Thus, in most cases, hyperprolactinaemia is usually a result of high levels of monomeric PRL, which may be due to excess production as with a prolactinoma or due to disinhibition by compression of the pituitary stalk. Nevertheless, it must be noted that macroprolactinaemia may be a cause of hyperprolactinaemia in some individuals, which may have no association with any pathology. The presence of macroprolactin should always be suspected when a patient's clinical history and/or radiological data are incompatible with his/her PRL value. Thus, it may be useful to screen all patients with high sera PRL levels in order to prevent unnecessary investigations into the cause for hyperprolactinaemia. This has recently been facilitated with the advent of simple laboratory tests such as the polyethyleneglycol precipitation method, although gel filtration chromatography remains the gold standard. It is hoped that macroprolactinaemia is included in the differential diagnosis of hyperprolactinaemia.
